FRANK 7H. DERBY, or 'ERIELPENNSYLVANIA, AssrGNo T0 ERIN FOUNDRY coMrANY, v or ERIE, PENNSYLVANIA, njco roRnrroN or PENNSYLVANIA HAMMER Application fil ed May 27,

Power hammers are usually provided with some means of adjusting the hammer carrying guides with relation to the anvil. The present invention is designedto improve this adjustment. In carrying out the invention wedges are used for adjusting the parts relatively to each other in two directions and improved means are provided for lockingthe wedges in adjustment and also for locking the wedges withthe parts on which they are adjusted so as to permit of a slight free movement between the uprights ofthe'hammer and the base. F eatures and details of the invention will appear from the specification and claims. V

A preferred embodiment of the invention is illustrated in the accompanying drawings as follows n Fig. 1 shows a front elevation of the hammer.

tending to a piston (not shown) ina cylinder 6. The uprights are tied together by rods 7 and 8 at the bottom and top respectively. Dies 9 and 10 are arranged on the anvil and hammer head. The uprights are yieldingly held on the base by means of bolts 11 which operate through springs 12 on the'uprights in clamping them on the base. WVedges 13 extend forward and back betweenopposing shoulders 14 and 15 on the base and upright 1929; Serial No. 366,245.

so that the wedge is locked-to move with the i wedge is provided with serrations 19 and a clamping plate 20 is provided with a perforation 21 through which the bolt 18 extends and is provided with serrations 22- correspon-ding'with the serrations 19 which serrations when the plate is clamped against the wedge by means ofthe bolt 18 lock the wedge definitely in adjustment. 5

The axis 23 of the bolt is slightly off-set from the peak 24: of the serrations 22. By

reason of this arrangement the plate maybe reversed on the bolt and thus give a finer adjustment than the full width of the serrations. j I

Lips 25 extend downwardly on the and back sides of the uprights and form laterally extending shoulders, one shoulder engaging the edge 26 of the base and the other lip being engaged by a wedge 27 which is arranged in a seat 28 on the edge of the base. The wedge 27 is locked with the baseby a tongue and groove 29. The wedge is provided with a slot 30 and serrations 31. A bolt 32 extends through the slot and a plate 33 corresponding to the plate 20, the bolt clamping the plate 33 against the serrations locking the wedge in adjustment in'the same manner as does the plate 20 onthe wedge 13.

'The wedges 13 adjust the uprights relativelyto thebase sidewise and'the wedges 27 adjust the uprights forward and back, or-

dinarilythe lip and edge 26. providing the proper adjustment but, if" desired, this may =be vari'edby shimming between the edge 26 and the lip 25.,- The-wedges l3 and 27 cross 9 each other, being arranged on different planes and it W1lll16= l10f6d that the tongue and groove connectionof the wedges 13 is with the upright and that the adjusting bolts 18 are carried by the upright. In the same manner, the wedges 27 have a tongue and groove connection 29 with thebase and adjusting bolts 32 extend into the, base, and project through slots 30. The wedges haveserrations 31 which are en'gagedbya plate 33 similar front to the plate 22. The plate 33 is clamped by a bolt 82 and the adjustment is secured in the same manner as with the wedges l3.

WVhat I claim as new is 1. In a hammer, the combination of a base; guide uprights on the base; opposing wedge shoulders on the base and an upright; a Wedge between the shoulders, said wedge having a tongue and groove connection with one of the shoulders; and locking means on the shoulder having the tongue and groove connection for the wedge locking the wedge in adjustment.

2. I11 a hammer, the combination of a base;

guide uprights on the base; opposing wedge.

shoulders on the base and an upright; a wedge between the shoulders, said Wedge having a tongue and groove connection with one of the shoulders; and locking means on the shoulder having the tongue and groove connection for the wedge locking the wedge in adjustment; and means yieldingly clamping the upright on the base.

3. In a hammer, the combination of a base; guide uprights on the base; opposing wedge shoulders on the base and an upright; a wedge between the shoulders, said wedge having a tongue and groove connection with one of the shoulders; and locking means on the shoulder having the tongue and groove connection for the wedge locking the wedge in adjustment comprising serrations on the wedge and serrations fixed with the shoulder, said serrations being clamped together.

4. In a hammer, the combination of a base; guide uprights on the base; opposing wedge shoulders on the base and an upright; a wedge between the shoulders, said wedge having a tongue and groove connection with one of the shoulders; and locking means on the shoulder having the tongue and groove connection for the wedge locking the wedge in adjustment comprising a slot in the wedge, serrations on the wedge, a bolt extending through the slot, and a plate having serrations clamped by the bolt against the serrations on the wedge.

5. In a hammer, the combination of a base; guide uprights on the base; opposing wedge shoulders on the base and an upright; 21. wedge between the shoulders, said wedge having a tongue and groove connection with one of the shoulders; and locking means for the wedge locking the same in adjustment and in fixed relation with the shoulder having the tongue and groove connection comprising a slot in the wedge, serrations on the wedge, a bolt extending through the slot, and a plate having serrations clamped by the bolt against the serrations on the wedge, the axis of the bolt and peaks of the serrations being out of register.

6. In a hammer, the combination of a base; guide uprights on the base; opposing wedge shoulders on the base and upright; a

wedge between the shoulders, said wedge having a slot th-erethrough and serrations thereon; a bolt extending through the slot; and a plate on the bolt having serrations clamped by the bolt against the serrations on the wedge for locking the wedge in adjustment, the peaks of the serrations being out of register with the axis of the bolt.

7. In a hammer, the combination of a base; guide uprights on the base; opposing wedge shoulders on the base and upright, said shoulders extending crosswise of each other, one laterally and the other forward and back; a wedge between the laterally extending shoulders; and a wedge between the forward and back. extending shoulders.

8. Ina hammer, the combination of a base; guide uprights on the base; opposing wedge shoulders on the base and upright, said shoulders extending crosswise of each other, one laterally and the other forward and back; a wedge between the laterally extending shoulders; and a wedge between the forward and back extending shoulders, said wedges being in different planes and crossing each other.

9. In a hammer, the combination of a base; guide uprights on the base; opposing wedge shoulders on the base and upright, said shoulders extending crosswise of each other, one laterally and the other forward and back; a wedge between the laterally extending shoulders; and a wedge between the forward and back extending shoulders, one of said wedges having a tongue and groove connection with the upright and the other wedge a tongue and groove connection with the base.

10. In a hammer, the combination of a base; guide uprights on the base; opposing wedge shoulders on the base and upright, said shoulders extending laterally and forward and back; a wedge between the laterally extending shoulders; a wedge between the forward and back extending shoulders, one of said wedges having a tongue and groove connection with the upright and the other wedge a tongue and groove connection with the base; and means locking the wedges in adjustment.

11. In a hammer, the combination of a base; guide uprights on the base; opposing wedge shoulders between the base and each upright, said shoulders at each upright extending crosswise of each other, one laterally and the other forward and back; wedges between the laterally extending shoulders; and wedges between theforward and back extending shoulders.

12. In a hammer, the combination of a base; guide uprights on the base; opposing wedge shoulders between the base and each upright, said shoulders at each upright extending crosswise of each other, one laterally and the other forward and back; wedges bemy hand.
